Each node canister has
indicator LEDs that provide status information about the canister.
Using the callout numbers in Figure 1,
refer to the tables for a listing of the node canister LEDs and a
description of the meaning of the LED activity.

Meaning
SAS Port 1 Link
1
None
Green
OFF
No link connection on any phys (lanes). The connection is down.
ON
The port is connected to at least one phy. At least one of the phys to
that connector is up.
SAS Port 1 Fault
2
None
Amber
OFF
No fault. All four phys have a link connection.
ON
This status can indicate several different error conditions:
One or more, but not all, of the 4 phys are connected.
Not all 4 phys are at the same speed.
One or more of the connected phys are attached to an address different from the
others.
An unsupported device is plugged in to this SAS port.
SAS Port 2 Link

None
Green
OFF
No link connection on any phys (lanes). The connection is down.

The port is connected to at least one phy. At least one of the lanes to
that connector is up.
SAS Port 2 Fault

None
Amber
OFF
No fault. All four phys have a link connection.
ON
This status can indicate several different error conditions:
One or more, but not all, of the 4 phys are connected.
Not all 4 phys are at the same speed.
One or more of the connected phys are attached to an address different from the
others.

Meaning
Battery status
5
Green
OFF
Indicates that the battery is not available for use. The battery might
be missing or a battery fault was detected.
FAST BLINK
The battery has insufficient charge to complete a fire hose
dump.
BLINK
The battery has sufficient charge to complete a single fire hose
dump.
ON
The battery has sufficient charge to complete at least two fire
hose dumps.
Battery fault
6
Amber
OFF
No fault. An exception to this would be where a battery has
insufficient charge to complete a single fire hose dump. Refer to the documentation
for the Battery status LED.
ON
A battery fault was detected.
Node canister system status LEDs

Meaning
Power
7
Green
OFF
No power is available or power is coming from the battery.
SLOW BLINK
Power is available but the main processor is not running; this state is
called standby mode.
FAST BLINK
In self-test.
ON
Power is available and the system code is running.
Status
8
Green
OFF
The system code has not started. The system is off, in standby, or in
self-test.
BLINK
The canister is in candidate or service state. It is not completing I/O
operations. It is safe to remove the node.
FAST BLINK
The canister is active, able to complete I/O operations, or
starting.
ON
The canister is active, able to complete I/O operations, or starting.
The node is part of a cluster.
Canister fault
9
Amber
OFF
The canister can function as an active member of the system. If the
node canister has a problem, it is not severe enough to stop the node canister from
completing I/O operations.
BLINK
The canister is being identified. There might or might not be a fault
condition.
ON
The node is in service state or an error exists that might be stopping
the system code from starting. The node canister cannot become active in the system until
the problem is resolved. You must determine the cause of the error before you replace the
node canister. The error might be due to insufficient battery charge. To resolve this error,
wait for the battery to charge.
